N6-Methyladenosine Methylation of mRNA in Cell Senescence

Cell Mol Neurobiol. 2023 Jan;43(1):27-36. doi: 10.1007/s10571-021-01168-2. Epub 2021 Nov 12.

Abstract

Cell senescence is the growth arrest caused by the accumulation of irreparable cell damage, which is involved in physiological and pathological processes and regulated by the post-transcriptional level. This regulation is performed by transcriptional regulators and driven by aging-related small RNAs, long non-coding RNAs, and RNA-binding proteins. N6-methyladenosine (m6A) is the most common chemical modification in eukaryotic mRNA, which can enhance or reduce the binding of transcriptional regulators. Increasing studies have confirmed the crucial role of m6A in controlling mRNA in various physiological processes. Remarkably, recent reports have indicated that abnormal methylation of m6A-related RNA may affect cell senescence. In this review, we clarified the association between m6A modification and cell senescence and analyzed the limitations of the current research.

Keywords: Cell senescence; N6-methyladenosine methylation; mRNAs.
